It is only useful if you know in advance the percentage of expected positive/negative results. So be careful how and where you apply it. You can end up with more work overall.
One way to approach this is to sample a small population first with individual tests to obtain an approximate percentage and then apply some statistical methods to reduce the number subsequent tests. This would require good unbiased selection criteria to start with.
